古钱币的市场如此火热,但高收益的同时造假猖獗.

       

1、翻铸法

此种方法以(yi)真(zhen)钱(qian)(qian)原品做模子捏(nie)造。浇铸铜(tong)水多(duo)为现代铜(tong)钱(qian)(qian)或铜(tong)镜熔解(jie)而成,是(shi)以(yi)翻(fan)铸铜(tong)质仍为青铜(tong)或红铜(tong)。由于(yu)热涨(zhang)冷(leng)缩原因,以(yi)成本翻(fan)钱(qian)(qian)要小(xiao)于(yu)成本,即翻(fan)铸小(xiao)一匝(za)。此种伪钱(qian)(qian)上市极多(duo),有的几可(ke)乱(luan)真(zhen)。

2、改刻法

抉择(ze)(ze)旧铜(tong)(tong)钱较厚(hou)的的磨去原有(you)笔(bi)(bi)墨,改(gai)刻(ke)另一(yi)种(zhong)稀(xi)见(jian)品来捏造。此种(zhong)捏造品为(wei)(wei)数(shu)不少。如(ru)五铢改(gai)刻(ke)为(wei)(wei)太清丰乐(le),小(xiao)货泉改(gai)刻(ke)为(wei)(wei)永(yong)光景和等。另有(you)抉择(ze)(ze)铜(tong)(tong)钱文(wen)制模糊的添刻(ke)笔(bi)(bi)墨或星月,如(ru)改(gai)刻(ke)半(ban)两为(wei)(wei)两两或半(ban)半(ban),改(gai)刻(ke)五铢为(wei)(wei)五五或铢铢。用各种(zhong)方(fang)法别树一(yi)帜。

3、粘合拼接法

此种(zhong)方法(fa)多用于连(lian)泉(quan)、合背、同(tong)(tong)文钱(qian)。取雷同(tong)(tong)品两(liang)至数枚(mei),磨去没(mei)钱(qian)的一部分,粘合拼接,即成连(lian)泉(quan)、合背或同(tong)(tong)文钱(qian)。另有磨去二个旧钱(qian)的背,拼合起来成为(wei)两(liang)面笔墨。

4、光彩作旧法

出土古钱历经百年(nian)公开腐(fu)化,有(you)的浑身葱绿(lv)、有(you)的红、绿(lv)、黄、白,斑班(ban)驳(bo)驳(bo),货币界称(cheng)为(wei)“活(huo)埋锈(xiu)”。传(chuan)世的古钱由于久长玩赏,油汗入(ru)表,钱体呈黄褐(he)或(huo)褐(he)色。作(zuo)伪者为(wei)获得“活(huo)埋”、“传(chuan)世古”的外面后果,湖南电(dian)视台《西方(fang)寻宝》报名:《一八六八四九二四二九九 》(编导)便在伪钱光彩上(shang)作(zuo)旧。罕(han)见的方(fang)法以(yi)下:

1、看铜质定真伪

古代铜(tong)(tong)钱的材(cai)质有青(qing)铜(tong)(tong)、白(bai)铜(tong)(tong)、红(hong)铜(tong)(tong)和(he)(he)黄铜(tong)(tong)四(si)种。明(ming)代嘉(jia)靖(jing)(jing)以前铸(zhu)钱材(cai)质一(yi)般都是(shi)青(qing)铜(tong)(tong),少量白(bai)铜(tong)(tong),红(hong)铜(tong)(tong)铸(zhu)币辽代较多。青(qing)铜(tong)(tong)容易断(duan)裂,断(duan)裂面无铜(tong)(tong)色(se),而将断(duan)裂面在石头上(shang)摩(mo)擦后(hou),铜(tong)(tong)色(se)即显(xian)。黄铜(tong)(tong)铸(zhu)币和(he)(he)铜(tong)(tong)雕母钱始于(yu)明(ming)代嘉(jia)靖(jing)(jing),如(ru)果发现明(ming)代嘉(jia)靖(jing)(jing)以前的黄铜(tong)(tong)钱币或铜(tong)(tong)雕母钱,可(ke)判定是(shi)后(hou)铸(zhu)无疑。

2、听声音定真(zhen)伪(wei)

古铜(tong)钱(qian)(qian)年代越久(jiu),钙(gai)化越严重(zhong),钙(gai)化后的铜(tong)钱(qian)(qian)失去铜(tong)的原声,用金属(shu)撞(zhuang)击声音(yin)沉闷,声音(yin)越小,时间(jian)越久(jiu)。凡(fan)是发现声音(yin)尖高(gao)的古铜(tong)钱(qian)(qian),说明没有钙(gai)化现象,可判定(ding)为新彷品。

3、闻气味定(ding)真伪

古钱(qian)币(bi)真品由于长期埋入地下,生有锈色,出土时会带有一股纯正(zheng)的泥土香味(wei),没有别地异味(wei)。而假钱(qian)带有伪造的锈色,有刺鼻(bi)的胶水(shui)味(wei)、松香味(wei)、生漆味(wei)等怪味(wei)。

4、观锈(xiu)色(se)定真(zhen)伪

古铜(tong)钱(qian)(qian)停止(zhi)流(liu)通后(hou),存放不(bu)当会(hui)生(sheng)锈(xiu)(xiu)(xiu)。传世古铜(tong)钱(qian)(qian)锈(xiu)(xiu)(xiu)层较(jiao)薄,且锈(xiu)(xiu)(xiu)在(zai)局部,钱(qian)(qian)面大部分呈古黑色。出土(tu)(tu)铜(tong)钱(qian)(qian)坑(keng)口不(bu)同锈(xiu)(xiu)(xiu)色不(bu)同。土(tu)(tu)坑(keng)出土(tu)(tu)的铜(tong)钱(qian)(qian),锈(xiu)(xiu)(xiu)层一(yi)般较(jiao)厚,锈(xiu)(xiu)(xiu)在(zai)一(yi)起的铜(tong)钱(qian)(qian)叩开后(hou),有“泛金(jin)”、“泛银(yin)”、“泛蓝”现象,“三(san)泛”现象是无(wu)法仿制的;
